US President Donald Trump has demanded reimbursement from countries that did not assist the United States during the conflict over the Strait of Hormuz. Trump said these countries should compensate Washington once the conflict ends. He made the remarks on Monday while highlighting the continued flow of oil through the key waterway.

In a social media post, Trump accused countries across the world of providing no help to the US during the crisis. He also argued that Washington has carried a greater burden for other nations for generations, while doing less for itself.

“The Countries of the World, which have been no help to us whatsoever, should, and will, reimburse the United States of America when this SCAM Conflagration is all over,” Trump said.

Trump added that the US has repeatedly done more for other countries than for itself. “We are doing it much more for others, than we are for ourselves, and we have been for Generations!” he wrote.

Tensions around the Strait of Hormuz have continued to rise. An Iranian commercial vessel came under attack early Sunday off Qeshm Island. One of its 10 crew members died, while four others suffered injuries, according to Iranian state media.

Iranian state-run IRNA quoted the Qeshm governor as blaming a "terrorist enemy" for the attack. He said authorities had not yet identified the projectile used in the strike.

Separately, the United Kingdom Maritime Trade Operations monitor reported that a vessel was hit by a projectile while passing through the strait. It did not provide further details about the incident.

The US military did not immediately comment on the attack. US forces had earlier struck Iranian-flagged vessels while maintaining a blockade of Iranian ports. At the same time, US warships have faced a new threat from Iranian ballistic missiles in recent days, according to the Associated Press.

Qeshm Island lies around 22 kilometres from the port city of Bandar Abbas. The island plays an important role in Iran's efforts to control maritime traffic through the Strait of Hormuz.

Sunday's attack came amid continuing tensions around the waterway. The strait was regarded as an international route before the US and Israel launched the war on February 28.

Iran and Oman have separately reached an understanding on new entry and exit routes through the Strait of Hormuz. The two countries are expected to brief other Gulf nations on the outcome of their discussions at a regional meeting in Muscat.

Semi-official Tasnim news agency, citing a source close to Iran's negotiating team, reported that the understanding followed intensive technical and diplomatic talks between Iran and Oman. The discussions reportedly ended with a final agreement in late August.

Under the proposed arrangement, the entry route from the Gulf would remain entirely within Iran's territorial waters. Part of the exit route would also pass through Iranian territorial waters, Tasnim reported, citing sources.
